Body composition is associated with multiple factors. The main objective of this study is to determine the association between diet and sociodemographic factors on the body structure and composition of university students at a public university in Ecuador. This cross-sectional study allowed for the collection of detailed body composition and dietary data from 204 students (41.7% men and 58.3% women, with an average age of 23.3 ± 4.4 years). The study was conducted using validated questionnaires and bioimpedance techniques. Statistical analysis included ANOVA tests, complemented by a PCA-Biplot, to examine the relationships between study variables. Statistical analysis revealed that men's birthplace had a significant impact on several body measurements, such as hip circumference and weight, but no significant differences were observed in body structure and composition based on nutrient intake. Furthermore, larger upper-arm circumference in women was correlated with higher fat intake. The results of the multivariate analysis indicated a differential influence of dietary components on body composition. The study highlights the need for nutritional intervention strategies and educational programs that consider the diversity of students' backgrounds to promote healthy habits and mitigate the negative effects of eating habits and irregular physical activity patterns on their health and body composition.
身体成分与多种因素相关。本研究的主要目的是确定饮食和社会人口学因素与厄瓜多尔一所公立大学学生的身体结构和成分之间的关联。这项横断面研究收集了204名学生（41.7%为男性，58.3%为女性，平均年龄23.3±4.4岁）详细的身体成分和饮食数据。该研究采用经过验证的问卷和生物阻抗技术进行。统计分析包括方差分析测试，并辅以主成分分析-双标图，以检验研究变量之间的关系。统计分析表明，男性的出生地对一些身体测量指标有显著影响，如臀围和体重，但基于营养摄入在身体结构和成分方面未观察到显著差异。此外，女性较大的上臂围与较高的脂肪摄入量相关。多变量分析结果表明饮食成分对身体成分有不同影响。该研究强调需要制定营养干预策略和教育计划，考虑学生背景的多样性，以促进健康习惯，并减轻饮食习惯和不规律体育活动模式对他们的健康和身体成分的负面影响。
